Sebapali sa mocheso oa sebōpi sa SMT-4 se sebelisetsoa ho lemoha kabo ea mocheso nakong ea ho roala ho netefatsa boleng. Lera la ho kenya mocheso le entsoe ka lisebelisoa tse sa fetiseng mocheso, 'me morero ke ho kenya mocheso. The friction block e entsoe ka lintho tse ferekaneng le sekhomaretsi, 'me e petetsoa holim'a diski ea brake kapa drum ea brake ho hlahisa likhohlano nakong ea braking, e le ho fihlela sepheo sa ho fokotsa lebelo le ho qhoma ha koloi. Ka lebaka la likhohlano, sekhahla sa likhohlano se tla felloa ke matla butle-butle. Ka kakaretso, ha theko ea brake pad e le tlase, e tla fela ka potlako.
